Honored Contributorcommunication with altera fpga starter kit.
hi, i have had this board lying around and i want to try something with it which does more than produces a pattern on the 4 LEDs.
there are these weird HSMC connectors which i cant see an rs232 board(or any board) for anywhere. is there any way i can use the JTAG connection to emulate a serial port so i can send/recieve bytes from hyperterminal. i noticed 4 wires in the schematic called Link1,2,3,4. could they have something to do with it? Is there some kind of megafunction associated with these that acts like a uart? Thanks for any replies. Lee4 Replies

I have deliberated on this idea sometime back. Here is a thread on a discussion on using JTAG as a serial port: http://forum.niosforum.com/forum/index.php?showtopic=4224&st=0&p=16504&#entry16504 --- Quote Start --- Is there some kind of megafunction associated with these that acts like a uart? --- Quote End --- Yes there are RS-232 cores available: http://www.altera.com/education/univ/materials/ip-cores/unv-ip-cores.html

In that case, you can use this daughter card to upgrade your board: http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=39&no=240 It is by Terasic Technologies and provides facility for RS-232 communication. It is also Altera partner board.
